APPARATUS FOR CHANGING SHUTTLES IN LOOMS.

' ratus for; mechanically and automatically shifting shuttles in looms and in carrying out the same, I employ a batten, a shuttle box movably mounted on the said batten, a fixed shuttle-box, a shuttle magazine, means for normally holding the movable shuttle-box in its normal position, a drive shaft, a mechanical moving device mounted on the said drive shaft, means for operating the said mechanical moving device and means through which the said mechanical moving device operates to move the said movable shuttle-box on the said batten, as will hereinafter be more particularly described.

In the drawing, Figure 1 is a side elevation illustrating my present invention and showing the batten and parts connected therewith at the end of the return stroke. Fig. 2 is a plan view of the parts shown in Fig. 1, showing the batten and the parts connected therewith nearing the end of the forward stroke. Fig. 3 is a side elevation illustrating the ositions assumed by the various parts whi e a shuttle is being shifted from the shuttle magazine to the movable shuttle-box. Fig. 4 is a side elevation illustrating the positions of the parts while an empty shuttle is being ejected from the fixed shuttle-box to a chamber adapted to receive the same, and Fig. 5 1s a detailed view in elevation illustrating a G mechanism for maintaining the means for actuating the movable shuttle-box in operation during the-required time for the shifting of the shuttle.

In the drawing, 1 designates a batten on which a shuttle-box 2 is fixed.

' 3 3 are conducting wires leading respectively from terminals at opposite sides of the shuttle-box 2 to an electro-magnet 4, a suitable source of electricity, not illustrated, being included in the circuit to complete the same.

5 designates a pin upon which a lever 6 is pivotally mounted, one end of the lever 6 forming an armature for the electro-magnet 4 and the opposite end of the lever 6 being bifurcated or fork-shaped and adapted to Specification of Letters Patent.

engage the sleeve 7 of the cou ling mounted on a drive shaft 8, by which 1; e loom is operated.

As will be readily understood, a shuttle of ordinary construction when entering the shuttle-box 2 will close the circuit through the electro-magnet 4, actuate the lever 6 against a suitable spring or other means for holding the same in a normal osition, whereby the sleeve 7 will be caused to slide a predetermined distance on the drive shaft 8. A cam-disk 9 suitably shaped to perform the functions hereinafter described, is loosely mounted on the said drive shaft 8 and rovided with a coupling member adapted to be engaged by a coupling member on the sleeve 7 when the same is shifted on the drive shaft by the movement of the lever 6 when an empty shuttle has entered the shuttle-box 2. A shuttle-box 10 is movably mounted on the batten 1 in any manner known to the art to which this inventionrelates. At one side and parallel therewith the movable shuttle box 10 is provided with an auxiliary chamber 11 adapted to receive an empty shuttle from the fixed shuttle-box 2 and from which auxiliary chamber 1 1 the empty shuttle may be readily removed. l

12 designates a roller suitably mounted in a frame 13 connected to the movable shuttlebox 10 in such a position that the said roller 12 will be engaged by the periphery of the cam disk 9 when the latter is actuated by being coupled to the drive shaft 8. On the side of the movable shuttle-box 10 opposite the auxiliary chamber 11,- I prefer to employ arms 14 adapted when the movable shuttle-box 10 is shifted to its extreme forward position on the batten, to engage the levers 16 adapted to remove the lowermost shuttle from the shuttle magazine 15.

The front wall or member 18 of the movable shuttle-box 10 is pivotally mounted and I employ a cord or chain 17 fixed at one end to a point on the batten, passing over a suitable roll or pulley and secured at the other end to the said front member 18 of the movable shuttle-box, so that when the said movable shuttle-box is shifted to its forward position on the batten, the said front member 18 will be raised in order to permit the lowermost shuttle as ejected from the shuttle magazine, to enter the movable shuttle-box 10, it being understood of course that in the return of the said movable shuttle-box, the front member 18 thereof will drop by gravity and the said movable shuttle-box is normally maintained in its normal position on the batten 1 by means of a pair of springs 19, each extending between the same and the said frame member 13.

20 is a sleeve slidably mounted on the drive shaft Sand engaged by one end of the lever 21, the opposite end of which is adapted to be engaged by a segment 22 secured to the cam disk 9, and in order to insure the cam disk 9 stopping in the desired or predetermined position, I'may pro vide the segment 22 with a notch 23 into which the free end of the lever 21 is adapted to enter.

In the operation of the hereinbefore described mechanism, the shuttle in the movable shuttle-box 10 becoming empty, is ejected into the fixed shuttle-box 2 whereupon the circuit to the electro-magnet 4 is closed, the magnet excited, the lever 6 actuated to operate the coupling and connect the cam disk 9 with the driveshaft 8, the cam disk 9 being revolved, engages the roller 12 and shifts the movable shuttle-box from its normal position to its forward position in the batten 1. In this forward position the pairs of arms 14 operate the levers 16 to eject a filled shuttle from the shuttle magazine 15 into the movable shuttle-box 10, the front member of which is raised through suitable means in the shifting of the shuttle-box on the batten.

It will be understood that the shape of the cam-disk 9 will not only be such as to effect the desired movement of the movable shuttle-box on the batten but also after this desired movement of the shuttle-box has been effected, to maintain the movable shuttle-box on the batten, so that while the shuttle which has entered the fixed shuttlebox 2 is being ejected therefrom to the auxiliary chamber 11, the relative movements of the movable shuttlebox and the batten are the same; that is to say,while the empty shuttle is being shifted from the fixed shuttle-box to the auxiliary chamber, the movableshuttle-box and the batten move together in unison. Of course after the empty shuttle has been removed from the fixed shuttle-box, the circuit to the electromagnet core is broken and the clutch would normally be released, but in order to maintain the uniform movement of the movable shuttle-box and the batten, the clutch members are maintained in their engagement by means of the sleeve 20, lever 21 and segment 22 on the cam disk 9, until the cam disk has completed a revolution, at which time the free end of the lever 21 drops into the notch 23 in the segment 22, and thereby releases the clutch members, stops the cam disk 9 and permits the springs 19 to return the movable shuttle-box 10 to its normal posioIperative upon a shuttle entering the fixed siuttle box for actuating the last aforesaid means.
